text: Mechanical alloying is akin to metal powder processing, where metals may be mixed to produce superalloys. Mechanical alloying occurs in three steps. First, the alloy materials are combined in a ball mill and ground to a fine powder. A hot isostatic pressing (HIP) process is then applied to simultaneously compress and sinter the powder.  A final heat treatment stage helps remove existing internal stresses produced during any cold compaction which may have been used.  This produces an alloy suitable for high heat turbine blades and aerospace components.
